Trying to get my 2600k to 5GHz and it's proving slightly difficult. I'm currently at 1.5v unstable and was hoping there are some stability tweaks unknown to me that might help me stay stable without increasing vcore by much more.

Ambient temp here is around 26-27c right now. At 1.5v I'm idle at 39-40c and between 74 and 80c under P95.

1.5v is pretty crazy. You should definitely lower that unless $300 for a new processor isn't a big deal. 5Ghz is a nice number but there is nothing wrong with settling for 4.4Ghz - 4.9Ghz. The chip will still be crazy fast.

Hate to say it but not every chip can get 5GHz+. Don't want to argue with anyone else but I think 1.5v+ is definitely pushing the envelope.

Thanks for the tip, and yeah, it really looks like I have one of the baddies. Unstable at 1.52v unfortunately. I'm not going to be running 1.52v 24/7 so there's really not much point in trying any further.

I don't think 1.5 is 'crazy', but it's definately not optimal. I can stay at a comfy 4.8 at 1.38v so that's where I'll stay I suppose.

Really freakin hot here right now. Temp sensor right in front of my top rad is reading 28c. 40c did seem to me like it was quite high for an idle but load temp seemed OK to me.. was hoping to get some more opinions on it

Longest run so far was something like 28 minutes peaking at 82c but mostly staying around 78.

28minutes? lol Not long enough to get a peak temperature reading. I recommend running it for a few hours, that way you get to see stability and also somewhat realistic temps, I say realistic, but as close to realistic as possible. Remember nothing will recreate those temps other than stress testing. Don't use IBT for reading temps, imho it's totally crap and unrealistic. It may be a quick 'dirty' way of telling stability, not really the case for Sandybridge anyway, but does a crazy job at getting those extreme high temps which is crap anyway.

If in everday usage nothing will get the temps higher than prime95 Custom blend with 90% or so of your available RAM then why on earth would you run IBT? I guess you could if you don't have time or your not that patient. It's been said countless times Prime blend is the best stability tester for sandy and can even stress it using some decent temps.

I personally would rather run 12hours of Prime blend and peak my temps at 70c rather than run IBT/LinX for 50/100 runs which might take 30mins I don't know and allow my temps to go to 85c.
